BOX-COVERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 527,913, dated October 23, 1 894.

Application filed February 20, 1894. derial No. 500.859. (No model.)

a pleasing finished appearance to the same.

My object is to produce a machine of very simple construction, which will be easily controlled by the operator and readily changed to suit different forms and sizes of boxes.

The invention is fully described in connection With the accompanying drawings and is specificallypointed out in the claims.

Figure l is a front elevation of my machine. Fig.2 is a side elevation of the same. Fig. 3 is a plan view. Figs. 4 and 5 are onlarged sectional views of the mandrel showing more clearly the manner of attaching the operating and spring straps respectively.

A represents an iron supporting frame, in the head stock at of which is mounted a mandrel C. On the nose of this mandrel is.

screwed a chuck B preferably made of wood formed to suit a particular form or size of box. To the opposite end of the mandrel, which may be enlarged in diameter as desired, are secured theends cl and f of separate flexible straps D and F of leather or similar material. These are arranged as indicated in Figs. 4 and 5so as to Wrap upon the mandrel in opposite directions.

The free end of the strap D is fastened to a rod E Which works in a guide a on the frame, and is provided with a foot piece or stirrup e at its lower end. This I call the operating strap becauseby moving the stirrup a downward from its normal position shown in the drawings the shaft is rotated to an extent corresponding with the amount of this downward movement, the strap D unwinding from the mandrel. Any suitable stop may be provided to limit this movement, as a projection e from rod E.

The free end of the strap F is fastened to the end of a spring G which is fixed at its lower end to the frame and is capable of considerable motion. In depressing the stirrup e the strap F is wound up upon the mandrel against the action of the spring G, which when the stirrup is released automatically returns the mandrel to its normal position.

In operating my machine the uncovered box is placed upon the chuck which it fits so as to be rotated with it. The paper which is cut to proper size is covered with paste and fastened along the top edge to the periphery of the box, and the stirrup e is then depressed thus rotating the box one turn while the operator presses the paper firmly against the rotating surface thus quickly and evenly applying the covering to the box. On relieving the stirrup a reverse movement is automatically given to the box by the action of the spring during which the operator presses his hand against the bottom edge of the box thus turning the surplus paper over against the bottom of the box and completing the operation, the finished box being removed from the chuck and replaced by another with the greatest speed and ease possible.

I do not limit myself to the exact construction shown as it may be modified Without departing from the spirit of my invention, but I What I claim is- 1. A box covering machine comprising a mandrel, a chuck secured thereto, means for imparting a limited rotation to said mandrel in one direction and a spring arranged to return the same to its normal position, sub stantially as set forth. 7

2. A box covering machine comprising a mandrel, a chuck secured thereto, straps E andD each having one end fixed to the mandrel and adapted to wind thereon in opposite directions, a spring attached to the free end of one of said straps and means for operating the other strap to rotate the mandrel, substantially as set forth.

3. A box covering machine comprising a mandrel, a chuck secured thereto, straps E and D each having one end fixed to the man- In testimony whereof I affix my signature in drel and adapted. to wind thereon in oppopresence of two Witnesses.

site directions, a spring attached to the free end of one of said straps, means for operating the other strap to rotate the mandrel, and WVitnesses: means for limiting the rotation to one turn, MORRIS H. SOHAFFER, substantially as set forth. S. W". REIFF.
